A XDA developer has released a fix for HTC One X which fixes the power management bug and boosts battery life by 10 to 20 percent

A XDA developer has spotted a power management bug within the Tegra 3 powered HTC One X which causes the device to drain out quickly.

The problem appears to be due to the misplacement of NvCPLSvc.apk app in the /system/bin directory instead of the /system/app directory.

To fix the problem the file needs to be placed under the right directory and the file’s permissions need to be changed appropriately. According to talkandroid, 'this can all be done using ADB to push the file to the right place on the handset, or by using a root-aware file explorer on the device to move the file and change the permissions.'

This fix some users have claimed has increased the battery life of their Android 4.0 run device to upto 20 percent, which is roughly about 5-6 hours.
